The latest creation to come from the World-renowned Thompson & Morgan plant breeding programme. Back in 2007, US customer Diane Engdahl of Santa Rosa, California, sent us seeds of an unusual cosmos growing in her back yard. Instead of having separate petals like most cosmos, all petals are fused into one single cup, completely changing the normally daisy-looking flower. Since then our breeders have been busy fixing the unusual trait across the colour mix, developing new shades and refining the habit of this uniquely shaped 'cupcake' cosmos. The result? An easy to grow, free-flowering three colour blend of single and semi-double blooms on tall bushy plants ideal for border designs and container growing. Cosmos 'Cupcakes' was the stand out performer in our 2014 flower trials, coping well and looking great come rain, shine or drought. This is our must-have flower for 2015, we just know you'll want to show it off to everyone. Height 1.2m (4').

White petals suffused with a vibrant shade of raspberry red that bleeds in from the edge of each daisy-like bloom.
